The Impact of Industrial Agglomeration on Urban Innovation: An Empirical Analysis in China

Based on the theory of industrial agglomeration affecting urban innovation, panel data 269 prefecture-level cities and above in China from 2011 to 2017 was used empirically analyze internal relationship between innovation. The study found that overall tertiary industry have a significant promotion effect while secondary does not significantly affect innovation; eastern cities, large medium-sized high-tech role promoting effects mid-western small-scale low-tech, medium-tech are obvious; has no impact innovation all regional large-scale with medium levels, low-tech also hinders However, improvement city's technological level, concentration industries gradually increased; Further analysis after using PSM model eliminate system differences, basic conclusion affects is still valid. threshold will increase degree agglomeration. It can be seen China's high-quality yet formed. findings provide theoretical basis for rational formulation policies promote
